The Maryland-based company will use the funds to expand sales and marketing efforts and accelerate product development.

In addition to the funding, Trusted Knight announced it has acquired Massachusetts-based Sentrix, a company that aims to protect against vulnerability exploits and DDoS attacks. The acquisition brings Sentrix’s Cloud-DMZ, a solution that offers an alternative to a web-application firewall.

The acquisition was finalized in December.

Also this month, Trusted Knight hired Doug Klotnia (pictured) as COO. Klotnia is an industry veteran with 15 years of experience operating and leading businesses. Prior to joining Trusted Knight, he was president of vPromos, a card-connected loyalty and mobile-marketing company.
